Summary
Predicted to enable several functions, including ATP binding activity; sulfonylurea receptor binding activity; and voltage-gated potassium channel activity. Acts upstream of or within several processes, including defense response to virus; response to exogenous dsRNA; and response to lipopolysaccharide. Located in myofibril. Is expressed in genitourinary system and heart. Used to study coronary artery disease and hypertrichotic osteochondrodysplasia Cantu type. Orthologous to human KCNJ8 (potassium inwardly rectifying channel subfamily J member 8). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) uses an alternate splice site in the 3' coding region, which results in a frameshift, compared to variant 1. It encodes isoform 2, which has a shorter and distinct C-terminus, compared to isoform 1.
